' ADDING-MACHI-`NE Application filed April 14, 1905.

17 cell w from t may Concern.'

Be it known that I Hanna C. PETERS, a citizen ol the United ltates, residing' at the city, county, and State of New York, have invented certain new and useful improven'xents in Adfling-lllachines, of which the following` is a specification.

My invention relates to vwhat are coinnionly known as addin machines, more especially to that type tici-eel" capable of printing, listing and adding or accumulatin individual items and of printing the tota thereof, such as a Burroughs adding machine, made substantially in accordance with Letters Patent of the United States Nos. 504,963 and V05,078, issuedA on Septenil'ier 12, 1893, on the inventions of William S. Burroughs, said machine bein further described in Patent No. 823,474, issued June 12, 1906, on the application of Alvan Macauley. The object oli my invention is to provide an adding machine of this general.' type or character with means for separately adding or accumulating the items of a series or plurality of dilierent columns and for keeping such accumulations or 'Iootings independently of the grand total or accumulation of all the items in the different columns, in such manner that, at the will of the operator, the machine may be caused to )rint the .footings or totals of the separate co mnns as well as the gra-nd total of all of the footings if desired. Moreover, according to the present embodin'icnt of my machine and by preference, I also provide for cross addition of the items in the dili'erent columns, so that when the usual accumulating,- niechansm of a Burroughs machine, for instance, is retained, the cross totals may be printed and separately accumulated into 'an independent rand total which, il the Work is correct, s iould equal the grand total of the separate footings ol the columns, in the resent instance, I have shown and I will 1ereiuaiter describe my invention as embodied in a machine of the Burrourrhs type, but it will be understood that my Invention is not limited in its' application or scope to such machine, but that the saine may be used in connection with machines of the' same general character and used for the same purposes.

proveniente embodied therein, the view henig of the left-hand side of the machine; Fig. 2 a plan view of the rearward portion 'of such machine; Fig. 3 a side elevation ot certain parts of a Burroughs machine, as well as certain details or parts of my improvements, the parts being shown full size and the view boing the left-hand side thereof; Fi 4 a view similar to Fig. 3 but ol the rig it-hand side of the parts; Fig. 5 a detail view of sonne of the vwarts constituting my improvements, this View being on a somewhat enlarged scale; Fivs. 6 and 7 details of certain parts concerned=` with the carrying mechanism; Fig. 8 an elevation of some of the parts or attacl'mients constituting my improvements; and Fig. 9 a perspective of the means for operating the parts illustrated in Fig. 8. A

Iuasniuch as the Burroughs niachine is well known as to construction and mode of operation and is also described as to its general principles in the Burroughs patents aforesaid, only those parts of the mechanisin will be explained or referred to which are more or less directly concerned with the construction and operation of my iiriprovements which, in the present instance, constitute attaclnncnts to the machine, whereby the additional results, hereinbefore referred to, may be attained.

As is well known, the Burroughs ma.- chine is provided with a keyboard having a series of ke ys 291 arranged in rows representing the different denomi nati ons, increasing from right to left and the keys of each row representing the digits 1 to 9. These keys are arranged to control or operate a series of stop wires or rods 270 which determine the degree of movement or descent of a series oi sectors, or racks 610 corresponding in number to the rows oi. keys, it being understood that in the operation of the machine a rack corres Jonding,l to a row of keys in which one of tie ke 's has been operated, is permitted to descend a distance correspondingin value to the particular' key operated or de nessed. Furthermore` ou a Burroughs machine these racks are normally locked in their raised position and remain in such condition until their retainers or locks 415 are removed from locking engagementtherewith, it being understood that each rack 1s provided with a retainer 415 which is operated by the' sliding bar 214 corresponding in number to the rows of keys and moved rearwardly whenever a key in that row is depressed.

The racks 610 are carried at the 'forward end of a series olf main levers or sector bars (Sill, corresl'ionding in number with the rows of keys and hrung,- intermediate their lcnvth upon a main transverse shaft (500. 'F he rearward ends of these levers carry the usual movable type plates 61S, any one of which is arranged to be presented to theV platen 1599 according to the degree of movement of the levers, as permitted by the racks and as determined by the particular key or keys operated.

The racks 610 eo )crate with a series of adding wheels or dlals 912 which are arranged in a. frame having the side plates 91() rocking on shaft 900, whereby such wheels may be rocked into and out of cooperative relation with their racks for the purpose of receivingl the value or amount from such racks and also for the purpose cleansing the total on the adding-Wheels to betra'nsferred to the racks in the operation of tak-l ing a total, Fig. 1. The construction and mode of operation of the accumulating n'ieehanism being so well known, itis unnecessary to describe thc same in detail, and it will, therefore, suliee to state that upon the first. movement or rocking of the main operating shaft, or of an. o ierating handle, if the handle is employed, tlie adding Wheel frame 910 is swung 'forwardly so as bo carry the adding wheel pinions 916 out of mesh with their racks, such rocking being brought. about through the medium of thev rocking lever 913 and the pitman 914. The raeks corresponding to the rows in which the keys have been depressed will descend distances coi-respending, in value to such keys, in which operation the rearward or ty Je bearing ends of the levers belonging to the operated racks will beV elevated or rocked upwardly corresponding distances so as to present to the platen the figures of digitsv corresponding to the operated keys. After the amount has been printed upon the paper on the platen, the aecun'lulating meehamsl'n is restored to cooperative relatlonsl'iip with the rue-ks 610, whereupon in the upward. or restoring movement of the racks 610, the

values are transferred te the adding wheels corresponding to the particular racks Which have been operated.

The mechanisn'i j ust described is that which is eonnnon and well known in a Burroughs machine and comprises those parts in connection with which the-parts constituting my invention or improvements operate. In general terms my improvements comprise a series or plurality oi. accufnulators which' are operated or controlled by the series of main leversor bars (ill, with the 'the are of movement of its rack.

`result that separate or iiulependent totals may be taken of the items comprised in the diierent columns and the totals may be separately transferred to the machine and printed, the construction and arrangement being such that this result is attainable whether the items are printed consecutively in vertical columns or cresswise of the sheet of paper in the different columns. FurtherH more, under the-present embodiment ol' my invention the Burroughs machine proper keeps a rand total of all of the items, with the result that the work may be proved by subsequently accumulating the totals of the accumulatore which represent the footing-S of the different columns. The total of. such lootiu's should of course equal the grand total siown by theregular adding wheels `particularly in Figs; 1', 3, 4 and 5, eaclii rack has a pin and slot enga ement with its lever 611, to which end enel lever has an upwardly projecting slotted plate 2 arranged to receive :a r1plin 3 projecting laterally from each ruck. 1e racks are'arranged to move upwardly Whenever their corresponding levers are operatedv or rocked on the shait 600 as an axis and iii-order to guide these racks they are provided with curved slots l through which the fixed transverse shaft 500 passes, each slot corresponding of course to 'l`lie rear# ward edge of these racks is provided with a series of teethA arranged to eopcrate with the series of pinions arranged 1n different groups, which )inions or groups of` pinions I wil hereina ter term `accumulaters, inasmuch as they serve to accumulate and not to indicate. The racks are norlually held separated from their levers a distance of one tooth against the tension of their springs l by n'leal'ls hereinafter' explained.

The aecuuullators are mounted on a trame movable transversely of the machine, and by preference, and as shown in the drawings1 such aeeumulators are arranged on and mov able with the paper earriaqe itself which is a laterally shiftable one of struction illustrated in Pike Patenth No. 595,864, issued December 21, 1897, and I will now proceed t0 describe these accumulatore according to their present illustrated construction and arrangenient, without inten- `the general coulOO tion of limitation thereto. Tt will first be understood that any number of accumulators may he euniloyed and the number of pinions comprised in cach group may he varied, the nmnber of pinions in each accumulator corres )ending to the number of rows of keys of tllie pal'tieular machine in which my invention nray he embodied. ln the resent. instance, as illustrated clearly in ,."ign 2, l employ a series of. Seven accumulators so as to accommodate and taire the independent footings of seven diilereut eolumns of figures on. a single sheet oi paoer, or of six dill'erent columns in the event t iat the last Aaccumulator on the right is employed to accumulate the cross' tetals of the independent iten'is, as hereinafter explained, but lt will he umlerstood that the number of these aecrunulators may he varied as desired and also that all of. the accumulatore need not he employed if present.

In'the present instance each accumulator consists of a series of nine similar pinions 5 which are mounted in a rocking frame or bail comprising; a transverse shaft (i and parallel side arms 7 which are pivoted at their lower ends upon a rod or shaft 8, F ige. 3 and 4. This rod or shaft extends between the two side plates 9 whichv are secured to or form a part of the end frame or brackets of the platen frame extended for the purpose. It will be understood that all of the pinions of the different sets or groups of aceuunrlutors are mounted on the shaft 6, with the result that the pinions may be rocked rearwardly or forwardly in the automatic: manner hereinafter described. For the purpose of limiting Vthis forward and backward increment of the rocking frame or bail. which carries the accumulators, the side arm 7 contacts with the pins or studs 10 and 11, as illustrated in Figs. 2, 3 and 4. Each acclunulntor is provided with means for lockingr the pinions and, in the present instance, such means consists of a series of rockingl hails or frames 12 pivoted at their lower ends upon a transverse rod 13, whose ends are secured in the side plates 9. The upper ends of these frames are provided with corresponding teeth 14: corresponding in number to the number of pinions in its accumulator, there being nine of such teeth in the present instance. Each locking device is normally held forwardly with yielding pressure, as hy .means of the spring 15, and the arrangenient is such that the pinions of the different accumulatore are always locked when swung rearwardly, and all of them are locked when swung forwardly with the eX- eeption of the particular accumulator which is presented to the series of racks 1. For the purpose of thus interfering with the action of the locking device of this particular accumulator and thereby permit the racks l to transfer their yalues'thereto, in the manner hereinafter exiluined, I provide suitable means comprising, in the present instance, an arm 16 secured upon the shaft 500 and projecting rearwardly with its free end ter minating in a. foot arranged .in the path of movement of one oil the side hars of each of the rocking frames 12 as they are presented in operative relationship with the machine. It will. be understood that this arm 16 holds the locking device of that accumulator only which is in operative position, as clearly indicated in Figs. 2, 3 and 4. Suitable trans`- fermcarrying mechanism, hereinafter described, .is provided, to cause each accumulator pinion, when it completes a revolution, to turn the next higher pinion in the series one step.

llhen an item or amount has been set up on the keyboard of the machine and the machine operated thelevers or bars G11 are rocked upwardly as to the rearward ends in the well known manner and the racks 1 corresponding to the particular levers which have been operated are likewise elevated or rocked upwardly after lthe accumulators have been rocked rearwardly in an automatic manner, as hereinafter explained. After the item or amount has been printed upon the paper on the platen 1599 the accunmlators are permitted to Ehe restored to normal position, that is to he rocked forwardly, with the result that the particular accumula- .tor which is in proper position to cooperate with the racks 1 will be put into mesh with their rack teeth and those pinions corre spending vto the operated racks 1 will, upon the restoration of the parts and the consequent downward movement of the racks, be turned or rotated distances corresponding in value to the values of the keys operated. In other words, the item or amount set up on the keyboard is accumulated on the particular accumulator in action at the time, in the present instance, Fig. 2, this accumulator being the fourth or middle one of the series of accumulators.

For the purpose of automaticallyr roeking the accumulatore forward an hackward, so as to en age their pinions with and disengage them rom the racks which actuate them, I rovide in the present instance the means w lich may now be described, consisting of a lever 29 fulerluned near its lower end upon the shaft 501,.Fi s. l, 2 and 8, with means for rocking sai lever to cause its upper end to swing the upper end of the accumulator frame rearward at the proper time, to disengage the accumulator pinions from the racks, and to permit it to swing forward again at the proper time to reengage said pinions with the racks. The shaft (i is provided, at the ends of the accumulator sections, with collars 30, `against which the upper end of the lever 29 bears.

As shown in Fig. 2tl1e right hand upper end of the lever 29 consists of a straight vertical ariu, at the lower end of which the lever is bent outwardly or to the left, at right angles, and thence extends downwardly to its pivotal support upon the shaft 501. The richt hand vertical arm of the lever is rigidly connected by la cross rod 31 with a lever 32 fulcrun'ied on the shaft 501 at the left sideo the machine, and project ingr below said shaft, as shown in Figs. 1 and 8. rlhe levers 29 and 32 fulcruined on the shaft 50]., and the cross rod 31 rigidly connecting them, thus forni. a rocking frame mounted upon said shaft. This rocking frame is operated by means of a pitman 33 somewhat similar' to the pitinan 914 which operates the rocking frame 910 of the regular accumulating section el the machine in the usual manner. '.lhe forward end of the pitman 33 has a ,sliding support near the front of the machine upon the cross rod 4h00, while its rear end is divided into two vertically projecting arms, whose extremities 33 and 33 are formed into hooks to eooperate with studs or other suitable projections upon the sides of the lever 32 of the rocking frame before described. A spring 41 connected to the pitinan near its forward end no1-mall)T holds itsnear end elevated, with its lower hooked arm 33"L in engagement with the stud 32 upon the lover 32 of the rocking frame, and with its upper hooked arm 33" disengaged from the stud 32 upon said lever The pit-mun 33 is rcciprocated backwardly and forwardly, to operate the rocking fran'ie' carrying the lever 29, by means of a short p ivoted arm or lever 34 which is mounted uponv the upper rear end of a supporting bracket 35 secured to the side frame of the machine, Figs. 1 and 9. This lever 34 carries at its upper end a laterally projecting stud o1- pin 36, which coperates with a' recess formed in the pitman 33 and compris ing a lower portion 33 and an upper portion 33, said portions heilig in the present instance, offset in relation to each other, as shown. A spring 37, conmaeted at its lower end to the pin 36 and at its upper end to a {ixerl point, yieldingly holds the lever 3ft in and returns it to its normal neutral position shown in Figs1 1, S and 9.

For the purpose of rocking the lever Bal and thereb)1 reciprocating the pitlnan 33, there is secured upon the rock shaft 800 of the nmehiue a cam plate 38- into whose path of movement the lower ond ol the lever 3ft projects. When the operating handle of the nia-chine is pulled forward and the shaft 800 thereby rocked rearward (in the usual manner) the can plate 38 will swing the lower end of the lever 3ft rearward and throw its upper end forward, thereby forcing the pitinan 33 in the latter direction. During the further rearward movement of the plate 38 its curved upper ed e will travel beneath the lower end of the ever 34- and hold the parts in their moved position until the upper edge of the plate passes rearward of and clears the lower end of the lever, whereupon the spring 3T will restore the latter to its normal vertical position, with its lower end at such time projecting into tho )ath of the return forward movement of tie plate 38; This will permit the pitman and connected parts to return to their normal position shown in Fig.- 1.

Innsmuch as the hooked lower end of the depending arm of the Pitman 33 is normally engaged with the stud 32 on' the lever 32 of the rocking frame, it follows that when the pitman 33 is forced forward as described, at therbe inning of an o Jeration of the machine,'t1e lower end ol the lever 32 and the rocking frame will be drawn forward and the upper end of the lever 29 be swung rearward, to disengage the wccumulator pinions 5 from the racks 1 and prevent the pinions being turned by the racks at the upward movement of thelatter; and when the operating handle has reached its limit of forwardI movement, and the cam plate 38 has passed rearward of and cleared the lower endof the lever 34, the return of the pitman 33- a-nd; connected parts to their normal position, as described, will cause the upper end of the lever 29 to be swung forward 'again andthe accumulator pinions permitted to rengage the racks, soas to be turned by the latter during their return downward movement.

In the manner and by the means described, therefore, the accumulator pinions 5 are dis engaged from the racks 1 at the beginning of: each operation of the machine and rengaged with them at the proper point during such operation, very much as the inions 916 of the regular addingwheels of t 1e machine are disengaged from the racks 61()` at the beginning of each operation and rengaged therewith. prior to the return u )ward moven'ient of said racks; and, as will e understood, at suoli operation of the machineA the amount of any items set up on the keyboard of the machine will be added upon the regular addin wheels 912 of the machine and be also aldded or accumulated upon the pinions 5 oft the particular accumulator which is at that time in register or cooperative relation with the racks 1.

By operating the machine in the ordinary way, therefore, a series of items may be listed in a vertical column upon a sheet 'of paper and acclnnulated upon the iinions of the corresponding accumulator. rhe paper carriage may then be shifted to bring another vertical colunin on the; pal'Jer to the printing point and the corresponding aeeumulator into register with the operating luCliS l, md a second vertical column of items be printed upon thcpaper and accumulated upon the second acciuunlator; and so on. In this nianner, il the paper carriage be initially set in its cxtreme right hand position, with the left hand accumulator which it carries in register with the operating racks, seven vertical eolmnns of items may be printed upon the sheet of paper, andv the total of each column be accumulated upon the corresponding accumulator pinions; while a grand total of all of the items in all of the columns will have been accumulated upon the regular adding wheels 9120i the machine.

For the purpose of printing at the foot of each vertical column of items the total of the items contained in such colun'm, thc following provision is made: A key stein 39, provided with a ltey or linger button 40 at its upper and, is pivotcd at its lower end to the pitinan 33 at a point a short distance in rear oi' the front end ol" the latter. By means of this key the rear end of the pitman maybe def'n'essed to disengage its lower hooked arm 33 from the stud 32* on the lever 33 oil the rocking fra-ine and to engage its upper hooked arm 33" with the stud 32 on said lever. The result of this disengagement of the lower arm of, the pitinan from and the engagement of its up per arm with the lever 32 of the rocking `rame will be that When the pitn'ian is forced forward, at the beginning of the operation of the machine, the upper end of the lever 29 will be swung idly forward and the pinions 5- be left in mesh with the racks l, during the upward movement of the latter. The pinions 5 will therefore be turned l'iaclrward until arrested in zero position, which will cause the type representing the amount previously acciunulated upon suoli pinions to be brought to the printing line, for the printing of the total. After such total has been printed the pinions 5 will be swung rearward, out of engagement with the racks, before the latter begin their return downward movement, so as toV leai-'c the pinions in zero position and consequently to clear such accumulator. Thiais due to the -fact that at the return movement of the operating handle or main rock shaft, and consequent forward move* ment of the cam plate 38 which operates the pitman-actuating lever 34, the upper end of said lever will bc swung rearward beyond its normal vertical position, and will force the pitman rearward beyond its normal position, and as the upper hooked arm of the pitman is at such time in engagcnient with V the stud 32 on the lever 32 of the rocking lframe which carries the lever 29 the upper end of the latter will be swung rearward beyond its normal position' and discngage the -pinions from' the racks. They will be held disen- ,staged thereifroni until, at the end of the opleration of the machine, the upper end of the cam. plate 3S passes forward of and clears the lower end of the lever 34 and the latter is acri'nittcd to resume its normal position un( er the influence ci' its spring 37. l

When the lrey 40 and rear end of the pitman 33 are depressed, for the printing of a total in the manner described, the upper portion 33" of thc notch or recess in the pitman is bron ht into cooperation lwith the pin 36 on the ever 34.

Provision is made whereby the depression of the lrey 40' releases all of the racks 610 and levers 611 of the machine (as does the depression of the regular total-key of the inachine) such provision consisting in the present instance of aswinging bail 43 composed of a pair of pivoted side arms having their upper ends connected by a cross bar or lstrip i2 lying immediately in rear of the projecting upper ends of the latches or detente 4:15 which normally hold the racks 610 in their upper position; and an arin or link 45 'piv- Voted to said hail at its iront end and at its roar oud resting upon a stud upon the frainc- Work and provided` with a pin 46 normally 'engaging a recess or curved notch 39 in the forward edge of the key stein 39. When the key 40 is depressed the pin 46 is forced out of said notch and the arm 45 thereby forced forward, swinging the upper end of the bai143 forward and discngaging all of the detents l15 from their corresponding racks 610.

-umu of items, and the accumulator pinions bc reset to zero. This printing of ythe total of each vertical column of items at the :foot of the column may be donc either at the end of the operation of listing each column ,of items, or it may be done after all of the columns, have been listed. If no totals are I irnted at the fonts of the sei-'eral columns until the last column of items has been listed., then the grand total ofxall of the items in all of the columns will.be exhibited upon the regular adding wheels 912 of the machine, and ,this total may be rinted upon the sheet `of paper and the `adding Wheels be cleared, after which the totals o-F the respective colmnns vmay be printed at the foots of the several columns by adjusting the paper carriage transversely ,of the machine to bring the several sets of accumulator pinions successively into register with the actuating racks and operating the machine in the manner heretofore described. If no precaution be taken tov prevent it, the printing of these totals of the respective columns will cause suoli totals to be accumulated upon the regular adding' Wheelsl 912 'of the machine, so

that when the totals of all of the columns have been printed at the foots of the columns the regular adding wheels 912 of the nia.- chinc will again exhibit the grand total of all of the items in all of the columns; and such grand total may again be printed from the regular adding wheels in the usual 1nanner, for the purpose of comparison and jus-` tification with the grand total previousl)T printed. ln the priutin of these grand totals :from the regular at' ding wheels of the machine, in the usual manner, the swinging frame o1' hail carrying the accunnilators at the rear of the machine may be sii/1mg backward and the accumulator pinions maintained out of engagement with the supplemental racks, so that these accumulators will not be allee-ted by -the taking of the total from the regular .adding wheels.

I'f it bc desi-red to Iprint :the -t-otal at the foot of each column as soon as the 1listingof the items in 4that aarticular column is completed, this may e done iby means of the kc)I 40 yin thc manner .heretofore described, in which event the amount of such tota-l may 'be permit-ted. to accumulate upon the regular adding wheels, or Aproper precaution may 'be taken to prevent it. Thus, to prevent it, the regular Atotal key 2650i? thelnach-inefmay be so manipulated that the pinions 916 of tlie regular adding -Wheels 912 will be fhcldout of engagement with Athe racks 610 -during both the downward and upward 'movement of -the latter, so that said :pinions and the adding -Wheels 912 will not bev affected 4by the lprintln-g of 'the |total at the foot of any given column by aneans of the `accumulator -piuions 'corresponding to such col.- umn. 'It no precaution bcrtakenatorprevent the totalsbeingaccumulated upon the regularaddiug wheels of the machine they will be so accumulated, and when lthe total of the last listed column has been ,printed at the foot of such columntheu'e ularadding wheels -will therefore exhibi twice the amount of-'the grand totalvof the itemsdn all of the columns, the fitems havinglbeeu first individually lacclunulated upon lsaid adding wheels vand having been again laccumulated upon them inithe printing-of the totals of the resiliective columns.

In -the use or operation of my machine thus fardesfribed I have Aassumed that a single -vertical column of items is'lirst listed, and then a second column, and then a-third, and so on up-to the maximum capacity of the machine, the total of theA items ineach column being accumulated upon the accumulato; corresponding to such column,..and `a grand total of all of the items being accumulated in the regular accumulator of'themachine. The machinemay, however, .be used for what ma)r loe-termed cross-addition, in which case tthe-liist item in .the irst col-umn maybe printed infpropejposition and the amount of it added upon the corresponding accumulator. Then the paper carriage may lic shifted to position to bring the second columnar space upon the pa )er to the printing point and the second sct o accumulator pmions into register with the racks, and the first item in the second column be then listed and Vadded upon the second accumulator; and so on with a series of items in a horizontal li ne in the several su ccessive columns. When one horizontal line of items has been thus listed the paper carriage may be set hack' to right hand position, and -a second item be listed in the first column and added upon the corresponding accumulator, and the :paper carriage ibe then shifted for the listing of the second item in the second column and the addition of i-'lu on the -sec-r ond accumulator, and so on, witi the result that 'when the bottom .of the sheet ot paper is reached -a series of vertical columns rot items will have been listcd,.and the .total of :the yitems in `.each oolinnn will have 4been accumulated upon the corresponding aceinmilaftor, 4as :under the other mode off use .and o eraltiouof .the machine lwhich. has been described. When .the ymachine is used =for crosseaddition, however, :the total of each 'horizontal line of items is to he accumulated, and is ftoibe printed .at 'the right hand cud of thc line, and in 4such case il employ the right Yhand set 4ol accumulator pimons for the lpurpose :of accumulating these line- .tota'ls, -so that the machine has capa-city for -one :less column of individual items than 10o where 4it is not aised Efor -cross addition.

W hen the machine is thus used lfor crossaddition -thc individual ,items .in each horizontal lineare accumulated-upon the lregu- 'lar .adding Wheels1912 of A,the machine as 105 the-37 are individually 'listed and 4added u on .the corresponding accumulatore, so -t iat when .the end of. the horizontal liuc is reached ,the 'regular Vadding Wheels .9.1.2 4exhibit .the total, of the items listed in such ,horizontal line. lllhis lxital yis then transferred to-the right'hand set of accumulator pinions, and the addino Wheels 912 cleared, byoperating the machine to take and print f a total in the usualfi'nanuer, such total-being 11.5 printed at -the right hand end ofthe line andthe amount of it being accinnulated lupon the rigl'lt hand setof pinions in the saine-manner as if it had been 'an item set up on the keyboard oflhemachine. This operation -iis repeated at the-end of cach horizontal line, with the result that when the last itenrtobe listed upon the sheet liasheen printed in the last column. the sheet will hear a ser-ies (in the present instance six) of veri tical columns Vof individual items, and a single columnof l inetotals; While each of the accumiilators inclu ding the accumula tor of the right hand line-total column, will have accumulated -upon it .thetotal of the items in the correspondiugl column. When this has been done a grand total may be immediately printed at the foot of the right hand column by operating the machine in connection with the key 4,0 in the manner heretofore described, such total being printf cd from the right hand set of accumulator pinions. rlhis would leave the remaining columns, at the left, containing the individual items, without any footings, and these footings may then be successively printed in the manner heretofore described, and the amounts he permittedl to accumulate upon the wheels 912, with the result that when the ootino of the right hand or sixth column ol' idividual items' has been Jrinted the regular adding wheels 912 of t e machine will have accumulated upon them a. grand total of all of the items .in the six columns, and this grand total should of course correspend with the grand total previously gpriut'- ed from the right hand set of accumulator piuions. ',lhe work will thus prove itself, so to speak', and the grand total printed at the lou-er ri ghthand corner of the sheet of paper will represent at lonce the total. of the series of items or amounts in the vertical line-total column at the right hand side ofthe sheet of paper, and the total el the foot-ings of the other six columns in the horizontal line at the bottom of thesheet of paper.

A machine equipped uuth my invention may be employed in still other ways, for obtaining other and different results, accord.

ing to the desire of the operator and the character ol the work to he done, of which it Will sullice to cite a single illustration. If it be desired to employ the machine for the purpose .of listing several successive series oi' items, and printing the total of each of suoli series at the end thereof and clearing the machine preparatory to printn ing the .items in the next series, While at the saine time carryingI in the machine a. total of all of the indiv1dual items listed, so that at the end, of the operation a grand total of all of the items in all of the series-may be printed, such work may he done in the following marmer: The regular adding wheels 912 of the niac-hine will in such case -be employed for accumulating and printi11 the totals of the several series of' items, and some one of the sets of accumulator pinions 5 will be employed for accumulating the grand total. of all of the items. Thus, assuniing any one set of said accumulatinpiuions 5 to be in registry with the racks l. (or assuming the machine to be provided with only a single set of said pinions), the grand total of all of the items listed may be accumulated upon said pinions in either one of two Ways, while the totals of the severalseries of items are independently accumulated upon the regular adding Wheels 912 andqprintod therefrom. 1f the machine be operated in the ordinary way, by simply setting yup the amount of-each item upon the keyboard and then o Jeratin the handle of the machine as usual, it wil be understood that each item will be added both upon the regular adding Wheels 912 and upon tho accumulator pinions 5 in registry with the racks 1, in the manner hereinheforc described. A series of items may he listed and accumulated upon both sets of wheels in this manner, and the total 0f them be then printed at the foot of the serios, and the regular adding wheels' 912 be cleared, by operating the machine in the usual Well known manner for the taking of a total and clearinfr the machine. At the taking of suoli tota and vclearing of the regular adding wheels the 'swinging frame or bail carryin fthe acoiunulator pin'ions 5 will be swung ackn'ard, to hold said pinions out of mesh with the racks 1, so that the latter will move idly up 'and down Without turning said pinion's, and thereby leave accumulated upon said pinions the total of the first series el items listed. This may be done by hand, or by a suitable connection with the regulantotal ke of the machine or the same result may caccomplished by depressing the key 40 at the end of the forward stroke of the operating handle and holding it depressed during its return stroke. These o 1- erations may be repeated indefinitely, tie footing of each series of items being printed from the' regular adding wheels 912 of the-machine, while a total of all the items remains accumulated upon the pinions 5. At the' end of the operation or series of operations a grand 'total of all the items may be printed from said pinions 5 b o J- cratiug the machine. in connection u'itli tlu key Lt() in the manner heretofore explained.

Another Way of accomplishing the same result is to maintain the accumulator piulons 5 out ol cooperation with the racks 1 during thelisting of the individual items, and permit them to coperate with said racks only during the printinga of the totals of -the severalseries of items; in which case such totals will be accumulated upon the pinions 5, so that at the end of operations said pnons will have accumulated upon them all of the totals of the several series of items, and thus exhibit a grand total of all the items, fromwhioh such a total 1n ay be printed in the manner explained.

When the machine is used for cross-addtion, i.n the manner .heretofore described, the regular autmnatic line-spacing' mechanism of the machine, by which the sheet. of paper is automatically advanced one lino space at each operation of the machine, will be disabled or held out of operation by suitable means. The line spacing may then be effected by turning the platen manually after listing each horizontal line of items,

or the paper in ay be auton'iatically advanced one line space after the printing of the linetotal at the end ol cach horizontal line by means sin'iilar to that illustrated and described in my other pending application, Serial No. 207,631, liled May l2, 1901, (Pat ent No. 1,028,133 issued June Ll, 1912) or by other suitable means.

It remains now to describe the transfer or carrying mechanism which l have provided for the accumulators 5, by means of which, when any pinion in any given accuy -inulator has completed a revolution the next higher pinion in the series is advanced one ste) in the usual n'ianner. The ineclianisin which I employ for this purpose is quite siniilar in operation to, although di51i'erent in form from, the mechanism provided -or the saine purpose in connection with the regular accumulatore or adding wheels 912 of the Burroughs machine. It is best shown in Figs. 1, 3, 4, 5, 6 and 7. Referring to Fig. 5, it will be seen "that, the supplemental or secondary racks 1, which operate' the accumulator pinions 5, are normally held separated from their carrying levers v611, against the stress of the springs 4, by means o'f pawls 18 hung upon the shaft 500 and provided with depending hooked arms 18" enga ing shoulders 1" upon the forward edges o the rack plates. If the hook 18" ofany pawl be disengaged frointhe cor esponding rack, in the position of the parts shown, the spring d will pull the rack downward one step, to its limit of movement, and consequently turn forward one step the )articular pinion engaged by such rack. lllaeh pinion 5 is provi .ed upon its side with a trip-arm 17 pro `jecting beyond the teeth of the pinion, and these trip arms 17 are adapted to coperate with the rearwardly projecting arms of' the pawls 18. Then any pinion completes a revolution its trip-arn1 17 will contact with and depress the rearwardly projecting arm of the corresponding pawl 18, and throw 4its depending hooked arm 18" forward, thereby dsengaging such hooked arm from. the corresponding rack plate if the latter be at the time in normal position. Inasmneh, however, as the rack plates are frequently out of normal position when the pinions coniplete their revolutions and operate the pawls 18 in the manner described, it is necessary to provide means .for holding the pawls 18 in their moved positions until the raclr plates return to normal position. For this purpose I employ a series of latches 20 hung u non a shalt 22 and provided with rearward y extending notched or hooked arms 20 adapted to cooperate with hooks 18 formed upon the pawls 18. Coiled springs 19 connecting the latches 20 with 'the paw s 18 serve to engage the latches with the hooks 18 whenever t 1e pawls 18 are operated by the trip arms 17.

yAt each operation of the machine, when the type-carrying and arm-carrying levers G11 'are lifted their rear ends rise th rough one ste i ol movement before the corresponding rac s 1 are moved `from .normal position, this being due to the fact that the pawls 18 normally hold the racks 1 separated from the levers U11 by such distance, against the stress of the springs 4;. When the rear ends .0f the .levers rise, therefore, the springs 4; (and the gravity o'if. the racks) hold the racks in normal. position until such lost motion is taken up, whereu )on the racks are then carried on 1upward liv and with the levers. Under the construction and arran ement of parts which' has been described, tie lifting of the racks 4will carr their lu .or shoulders 1 upward away rom the looks 18h of the pawls 18, the latter remainin at rest or unalfected 'by such lifting of vtie racks. During such upward movement of the racks the accumulator pinions 5 will ordinari] .be swimg rearward, out .of engagement wit i the racks, as heretofore explained, but will be swung forward and engaged with the racks prior to the return downward movement; of the latter. If now during such return downward movement of the racks, and consequent turning of the pinions engaged by them, any given pinion be turned past its point of complete revolution its trip `arm 17 will Contact with and depress the rearw ardly projecting arm of the corresponding pawl 1S, thereby swinging the depending arm of said paw] forward and carrying its hoolr 18b out of the path of the return movement of the lug or shoulder 1" upon the rack which coperates with the next lii her pinion in the series, and the pawl will Je held in such moved position by its latch 20, as heretofore described. When such rack, in its return movement, reaches its normal position it will not be arrested .(as usual) by .the engagement of its lug 1'l with the hook 18" of the pawl 18, because the latter has been swung out of its path and is held by the-correspondu ing latch 20. Such rack will therefore move on downwardV witl'i its lever G11, one step beyond normal Josition, and thereby advance the pinion mesiing with it one extra step to eilect the transfer.

For the purpose of tripping all of the latches 2O at cach operation ol the machine, to permit the operated pawls 18 to return to normal position after having been moved by the trl p arms 17 ol the piuions, .l provide a tripping har 9.3 which overlies, and in the present instance is provided with notches 23 to embrace, the rearwardly projecting arms of the latches 20. As best shown in Fig. 6, this notched bar 23 is hung at its opposite ends in a pair of side arms 24, which are secured at their forward ends to the rock shaft 22 upon which 'the latches 20 are hung. 'lliis shaft 22 is rocked at each operation of the machine by a .bell crank 25 hung upon the shaft S01. As host shown in Fig. 1, the upper end olf the resu'wnrdly curved arm of' this hell crank is pivotcd at 2G to the right hand one ol' the two side arms 24 which carry the trip har 2b', while the depending vertical nrm olf the bell crank projects into the path olf movement ol the shaft or rod 704- carricd hy the arms 711 mounted at their lower ends upon the shaft; 703. 'lhe rod 704; is the rod which carries the trilil'iing pawls of the printing lnecluniisin in the regular Burroughs machine, and is swung forward at each operation of the nnrchine, and in the present 'instance contacts with the depending arm olf the bell crank 25 and swings its rea-P n'ardly curved erm slightly downward, thereby delin'essing the trip ber 23 and with it the reurwnrdly projecting horizontal arms ol ull o l' the latches 2O and disengaging their hooked rear ends 'from any of the pawls 18 tha-t may have been enga fed therewith, this operation occurring at tie proper time to permit the pawls 18 to resume their normal: position lor ropcrution with the shoulders on the rack plates. The trip bar 23 and associated ports are yieldingly held in and rcturned to their normal positions hy u. spring 28 connected at its upper end to a fixed point and at its` lower end to a depending,l curved arm 27 projectie from one of the side arms 2-1 'which carry the trip bar 23.

The pawls 1S not only perform the funcv tion which has been explained, but their rear ends 1S -in the present instance serve as stops to arrest the accumulator pinions at zero position when they are turned backward in the taking of a total, as heretofore described, the ulirupt sides of the trip arn'is 17 at such time contacting With the rear ends oi the pawls 18 and arresting the pinions :it4

the proper point.
